make random number in C# code example

Example 1: c# random int

Random rnd = new Random();
int number  = rnd.Next(1, 10);

Example 2: get random number c#

Random rnd = new Random();
int month  = rnd.Next(1, 13);  // creates a number between 1 and 12
int dice   = rnd.Next(1, 7);   // creates a number between 1 and 6
int card   = rnd.Next(52);     // creates a number between 0 and 51

Example 3: c# random

Random rnd = new Random();
string[] malePetNames = { "Rufus", "Bear", "Dakota", "Fido",
                          "Vanya", "Samuel", "Koani", "Volodya",
                          "Prince", "Yiska" };
string[] femalePetNames = { "Maggie", "Penny", "Saya", "Princess",
                            "Abby", "Laila", "Sadie", "Olivia",
                            "Starlight", "Talla" };

// Generate random indexes for pet names.
int mIndex = rnd.Next(malePetNames.Length);
int fIndex = rnd.Next(femalePetNames.Length);

// Display the result.
Console.WriteLine("Suggested pet name of the day: ");
Console.WriteLine("   For a male:     {0}", malePetNames[mIndex]);
Console.WriteLine("   For a female:   {0}", femalePetNames[fIndex]);

// The example displays output similar to the following:
//       Suggested pet name of the day:
//          For a male:     Koani
//          For a female:   Maggie
